Dear Alan,

Thanks for commenting! Regarding your question, it’s better to scan at 250 dpi, as opposed to increasing the resolution from 50 to 250 post-scan. This is because you will be able to pick up the fine details from the physical model in the initial scan instead of assuming that there is no small difference in the part along that area. For instance, for a flat plane there wouldn’t be a big difference if you scan at 250 dpi or 50 dpi, but for a tight curve of a part or a small feature (like a chamfer or sharp edge) you would gain much better clarity to the actual positioning of the feature at a higher resolution of 250 dpi.

If you can, it’s always better to get the best quality scan data you can because scan quality only goes down after post-processing. You can’t get better quality data than you originally capture.

I hope that answers your question. If you have further questions. Please feel free to contact us.

Lyman, thanks for your kind words. We really appreciate that you came to us for your 3D scanning project and we’re happy to help you out whenever we can.

Thanks for your feedback Gerd! It would be an ambitious project to review all the 3D scanning systems available in the market. However, we are looking to write a resource on different types of measurement tools for comparison, so please stay tuned.
